  3. 3. Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid sprawl. It also advocates compact, transit- oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. -wikipedia

  20. 20. Ra in garden Bio -Infiltration Det ention3 1 2 4 5 Roof Runoff 1. RAIN GARDEN Roof runoff is directed into rain gardens located at either end of the plaza. Storm water will be detained, filtered and infiltrated back into the soil. Any water that does not infiltrate will be slowly released into the Bio-infiltration planter. 2. BIO-INFILTRATION PLANTER Surface run-off and run-off released from the rain garden is directed into a central bio-infil- tration planter. This is planted with native veg- etation that will help filter out particulates and pollutants from the water as it moves towards the inlet. Any water that does not infiltrate back into the soil will be slowly released into an un- derground detention system. 3. INFILTRATION BED A centrally located gathering space will be comprised of a variety of pervious pavements (gravel, wood deck and grass) above a structural soil infiltration bed. This will reduce the amount of im- pervious surface on site by approximate 30% and will allow surface runoff to infil- trate on-site without entering a structured system. 4. DETENTION SYSTEM An underground detention system will be located within the infiltration bed. Any runoff that does not infiltrate back into the soil will be detained in this system and slowly released into the city’s sewer system. 5. DISCHARGE Any runoff that remains after circulating through this series of Best Management Practices interventions will be released into the city sewer system at an appropriate rate.
